The followers L L' are prevented from descending beyond the desired point by projectionsk in the moulds, and they rise level to'or` a little above the surface of the table. To'prevent the bricks from adhering to the followers, said followers are oiled after every action of the plungers, the oil being introduced automatically from cups m, from which it passes down through suitable channels to pieces 7L, of lannelfor other absorbent material, and as the table reciprocates under these pieces of flannel, the followers are oiled. Instead of-'connecting the followers by al lever, M, as shown in the drawing, they might be connected by toothed segments and racks, or by any other suitable mechanism.

The operation is as follows: By the action of the pug-mill the tempered clay is. continually forced out through the spout E, and after reaching the channels F F' the clay remains for a short time at rest., As the table moves in the direction of the arrow marked thereon 4in fig. 3, while at the same time the plunger J rises and the plunger J descends, the clay which has accumulated before the feeder K is pushed along in the direction of said arrow, and a portion o f the same is forced into the press-box G', which fills with clay as its plunger..

rises. When said plunger has travelled through one half o f its stroke, the table, with'the feeder, remains stationary, and no more clay is fed to the press-box G', During this time, and while the table remains stationary, the empty space behind the feeder is charged with clay, and as the table recedes, this clay is forced into the press-box G, and at the same timethe plunger J" descends and cuts off the clay Acontain-edili the press-boxvG' from the channel F', just enough being retained in said box to form a brick. In the mean time, the mould Ilis carried und-er the press-box G', and -as the plunger J continues t'o desend, this clay is forced into said mould,

and thereby a brickis finished. At the same time the follower L descends to'make room furthe clay, and the;

follower L rises. At this moment the tablereturns again in the direction of the arrow marked on it, and the plungerJ descends, and as the mouldI arrives under the press-box G, the follower -L is 'depressed and the fol lower L' rises, :thereby pushing out the brick previously formed in the mould I'. It/-is obvious,` that instead of arranging only one pair of moulds in the reciprocating table, two or more pairs might be arranged in one and the same-table, to operate in combination with a. corresponding number of press-boxes.v

What I claim as new, and desireto secure by Letters Patent, is-' l The channels F F', extending in opposite directions from the tapering spout E,land carrying the compressed clay to the reciprocating table-H, substantially as and for the'purpose set forth.

2. The feeder K, in combination with the lreciprocating table H, moulds I I', an'd press-boxes G G', con-'e K structed and operating substantially as and for the purpose set forth.`

3. The rocking-lever M, carrying the followers L L', and operating in 'combination with the reciprocating table H, moulds I I', and press-bones G G', substantially as and for the purpose described. i

4. The recesses h in the press-boxes G G', lto allow the surplus clay to escape, as set forth.

5. The pieces of flannel, or other absorbent material, supplied with oil from cups m, in combination with the reciprocating table H, moulds I I', and followers L L','constructed and operating substantially as and for the purpose described. l 4 y I This specification signed by me, this 5th day of June, 1867.
